Cosmic radiation destructive interference

If cosmic electromagnetic radiation could be deflected by interaction of opposite broadcasted electromagneticwaves, it may be possible to re-locate incoming waves around a ship through destructive interference.

I had proposed the idea to a professor of mine, he told me that the problem would be knowing what wave to broadcast in order to correctly “destruct” the incoming waves.

I don’t quite understand ehat exactly heat is. Confusion arises when thinking of blackbody radiation which deals with heat as elecromagnetic waves and yet fire is not thought of as waves.
